Description

Technical Field

[0001] The present application belongs to the technical field of water quality sampling, and specifically relates to a stratified water quality sampling and classification storage device. Background Art

[0002] In water quality monitoring, the physical, chemical, and biological properties of different water layers vary significantly vertically due to factors such as light, temperature, and currents. For example, surface water, affected by sunlight, has higher dissolved oxygen levels and is rich in algae and other plankton. Meanwhile, bottom water, likely due to oxygen consumption by the decomposition of organic matter, has lower dissolved oxygen levels and is rich in pollutants such as sediment and heavy metals. Therefore, stratified sampling allows for the acquisition of water samples from each layer, accurately reflecting these differences and providing detailed data for a comprehensive understanding of the true state of the water body.

[0003] Traditional water quality sampling equipment often uses fixed-length sampling rods for stratified sampling, or requires frequent replacement of sampling tools of different lengths. This is not only cumbersome to operate, but also difficult to precisely control the sampling depth. This can easily result in the collected water samples not accurately reflecting the true water quality of each water layer, seriously affecting the accuracy and effectiveness of water quality monitoring data. Furthermore, while some equipment has stratified sampling capabilities, the sampling process often requires technicians to manually operate various components, such as manually opening the sampling port and moving the sampling container. This complex operation not only consumes a lot of manpower and time, but is also prone to operational errors in complex field sampling environments, reducing sampling efficiency. Summary of the Invention

[0004] The purpose of this application is to provide a stratified water quality sampling and classification storage device to solve the problems raised in the above background technology.

[0016] Compared with the prior art, the present invention has the following advantages:

[0017] (1) The depth of the sampling tank in the water body can be accurately adjusted by the self-locking telescopic rod. At the same time, combined with the linkage design of the driving component, the opening and closing component and the sampling component, the sampling tubes with different numbers can be accurately moved to the bottom of the through hole in sequence to collect water samples, thereby realizing orderly and accurate stratified sampling of water samples from different water layers. Compared with traditional sampling equipment, this design avoids the problem of confusion in water sample collection, and through the sequential rotation of multiple sampling tubes, multiple water layer samples can be obtained without multiple adjustments to the equipment position, which greatly improves the sampling efficiency and ensures that the collected water samples can truly reflect the water quality of each water layer.

[0018] (2) By utilizing the drive assembly, the servo motor drives the driving gear, driven gear and other components to realize the automatic operation of the sampling tube movement and the opening and closing of the baffle, so that in the complex and changeable field sampling environment, the operation difficulty and labor intensity can be significantly reduced, the possibility of operation errors is reduced, the sampling time is saved, and the labor cost is effectively reduced.

[0028] Example 1:

[0029] See also Figure 1 、 Figure 2 、 Figure 4 as well as Figure 6 As shown, a stratified water quality sampling and classification storage device includes:

[0030] The sampling canister 1 includes an upper shell 2 and a lower shell 3. A self-locking telescopic rod 4 is installed on the top of the upper shell 2, and a control switch 5 is provided at the end of the self-locking telescopic rod 4. An opening and closing component 6 is provided on the upper shell 2, and a sampling component 10 and a driving component 19 are provided inside the lower shell 3;

[0031] As can be seen from the above, when sampling, the self-locking telescopic rod 4 is adjusted according to the water layer to be sampled, and then the technician holds the self-locking telescopic rod 4 to place the sampling tank 1 into the water body. At this time, the drive component 19 is controlled by the control switch 5 to operate, thereby driving the opening and closing component 6 and the sampling component 10 to operate at the same time to sample the water body. Subsequently, the self-locking telescopic rod 4 is adjusted again to move the sampling tank 1 to water bodies of different depths, thereby sampling water layers of different depths through the opening and closing component 6 and the sampling component 10.

[0032] Specifically, regarding the above-mentioned opening and closing component 6, refer to Figure 2 and Figure 3 As shown, the opening and closing assembly 6 includes a through hole 7, which is opened at the top of the upper shell 2 and penetrates to the inner side of the upper shell 2. A plurality of baffles 8 are provided on the top of the inner side of the upper shell 2, and the plurality of baffles 8 are connected by a connecting rod 9.

[0033] As can be seen from the above, when sampling, the multiple baffles 8 are driven to rotate by driving the connecting rod 9, so that the baffles 8 cannot block the through hole 7. At this time, the water in the water body is injected into the sampling tank 1 through the through hole 7, thereby facilitating subsequent sampling.

[0034] Specifically, regarding the above-mentioned sampling component 10, refer to Figure 4 and Figure 5 As shown, the sampling assembly 10 includes a plurality of sampling cylinders 11, each of which is provided with a retaining ring 12 at its bottom end. A transmission shaft 13 is rotatably connected to the bottom inner side of the lower shell 3. Drain pipes 14 are symmetrically installed on both sides of the lower shell 3. A movable plate 16 is provided on the inner side of the lower shell 3. A sealing ring 17 is provided at the edge of the movable plate 16. A plurality of placement grooves 18 are provided on the movable plate 16.

[0035] As can be seen from the above, when sampling, the movable plate 16 on which multiple sampling cylinders 11 are installed is driven to rotate by the transmission shaft 13, and the numbered sampling cylinders 11 are moved to the bottom of the through hole 7 in turn to sample water bodies at different depths, and the collected samples are temporarily stored inside the sampling cylinder 11; and when the sampling cylinder 11 rotates, water will be injected into the sampling tank 1 through the gap, and at this time it will be discharged through the drainage pipes 14 on both sides, and the one-way valve 15 is set to prevent water from being injected into the sampling tank 1 from the drainage pipes 14 on both sides.

[0036] Preferably, the upper shell 2 is movably mounted on the top of the lower shell 3 through threads, and a plurality of baffles 8 are arranged at the bottom of the through hole 7, and the baffles 8 are larger than the through hole 7;

[0037] As can be seen from the above, after sampling, the upper shell 2 and the lower shell 3 can be disassembled to facilitate the removal of multiple sampling tubes 11 containing samples; at the same time, the baffle 8 covers the bottom of the through hole 7 to prevent external water from being injected into the sampling tank 1.

[0038] Preferably, the end of the connecting rod 9 extends to the interior of the upper housing 2, and the connecting rod 9 is installed on the top of the transmission shaft 13, and the multiple baffles 8 are respectively arranged on the top of the multiple sampling cylinders 11, and the multiple baffles 8 and the sampling cylinders 11 are staggered;

[0039] As can be seen from the above, the connecting rod 9 rotates with the transmission shaft 13. When sampling, multiple sampling tubes 11 move to the bottom of the through hole 7 respectively, and the baffle 8 moves to the side of the through hole 7 accordingly, so that water is collected into the sampling tube 11; after the sampling is completed, multiple sampling tubes 11 move to the side of the through hole 7, and at this time the baffle 8 moves to the bottom of the through hole 7, thereby blocking the water injection.

[0040] Preferably, the plurality of sampling tubes 11 are respectively inserted into the plurality of placement slots 18, and the movable plate 16 is installed on the transmission shaft 13;

[0041] As can be seen from the above, before sampling, multiple sampling tubes 11 with digital numbers are respectively inserted into multiple placement slots 18, and the position of the sampling tube 11 is limited by the retaining ring 12. During subsequent sampling, the movable plate 16 is driven to rotate by the transmission shaft 13, thereby facilitating sequential sampling; after the sampling is completed, the multiple sampling tubes 11 are taken out accordingly to facilitate subsequent water quality testing.

[0042] Preferably, the drainage pipes 14 on both sides are arranged on the top of the movable plate 16, and a one-way valve 15 is installed on the drainage pipes 14 on both sides;

[0043] As can be seen from the above, when sampling, excess water will be injected into the sampling tank 1 . At this time, the excess water will be discharged through the drainage pipes 14 on both sides and the one-way valve 15 .

[0044] Example 2:

[0045] refer to Figure 6 As shown, the drive assembly 19 includes a driven gear 20, which is fixedly mounted on the transmission shaft 13. A servo motor 21 is mounted inside the lower housing 3. The output terminal of the servo motor 21 is connected to a drive gear 22. A battery pack 23 is provided inside the lower housing 3.

[0046] As can be seen from the above, the servo motor 21 is controlled by the battery pack 23 and the corresponding electrical components, so that the servo motor 21 drives the driving gear 22 to rotate, thereby driving the transmission shaft 13 to rotate following the driven gear 20 through the driving gear 22.

[0047] Preferably, the driven gear 20 is disposed on one side of the driving gear 22, and the driven gear 20 is meshed with the driving gear 22;

[0048] As can be seen from the above, the driving gear 22 can drive the driven gear 20 to rotate, causing the transmission shaft 13 to rotate, thereby transmitting power to the opening and closing component 6 and the sampling component 10.

[0049] Although the embodiments of the present application have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present application, and the scope of the present application is defined by the appended claims and their equivalents.
